解决y7000笔记本ubuntu下wifi无法连接问题

查看wifi与蓝牙硬件开关，发现ideapad的硬件模块都是关闭的

rfkill list all

打开终端

输入

sudo gedit /etc/rc.local

写入以下内容 进行保存

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

echo "" |sudo modprobe -r ideapad_laptop
exit 

为了保证重启生效，需要给予权限 终端输入

sudo chmod  /etc/rc.local

然后输入

reboot

重启后发现wifi正常使用，但是信号远比WIN要差切容易断

解决方案

sudo apt-get install git build-essential linux-headers
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
reboot
